摘要
"滇东黔西"盆地群埋深在2000m以浅的煤层气地质资源储量超过1×10^12m^3,属于大型气田。研究区老厂雨旺区块就位于滇东地区,地质结构相对简单,是煤层气勘查的重点有利区域。本文基于研究区煤层地质条件和排采工程实践经验,分析研究了该区块煤层气井排采特征,进一步总结并优化出一套更加适合该区块地质条件的排采工作制度,以期对该区域未来煤层气勘探开发有所帮助。
East Yunnan and West Guizhou basin group,whose geological reserves of CBM with burial depth less than 2000 m exceeds 1×10^12m^3,belongs to a large gas field.The research area,Yuwang Block of Laochang area is located in the east of Yunnan Province.With relatively simple geological structure,it is the key favorable area for CBM exploration.Based on the geological conditions and practical experience in the research area,this paper analyzes and studies the characteristics of CBM drainage,and further summarizes and optimizes a set of drainage system which is more suitable for the geological conditions of this block,so as to would be helpful for the future exploration and development of CBM in this area.
